Evaluate the expression when y = 4 y/2-8

Answer:

None of the above

Step-by-step explanation:

Given

[tex]Design = 2^4[/tex]

Required

Determine the degree of freedom (df)

df is calculated as follows;

[tex]df = N- 1[/tex]

In this case:

N = Number of designs,

[tex]N = 2^4[/tex]

[tex]N = 16[/tex]

Substitute 16 for N in [tex]df = N- 1[/tex]

[tex]df = 16 -1[/tex]

[tex]df = 15[/tex]

Hence, none of the options answer te question

Answer:

64

Step-by-step explanation:

First, we multiply by 4 on both sides to get rid of the pesky fraction. We get:

x - 24 = 40

Now we add 24 on both sides to isolate the x and get all of the numbers on the other side:

x = 64

To check our work, we can input our answer back into the equation:

(64)/4 - 6 = 16 - 6 = 10

This satisfies the equation. Therefore, x = 64 is our answer!

Answer:

x = 16°

Step-by-step explanation:

The three internal angles of the triangle are:

180° - 91° = 89° (angles in a straight line)

180° - 105° = 75° (angles on a straight line)

x = x (vertical angles are congruent)

x + 89 + 75 = 180 (sum of interior angles of a ∆)

x + 164 = 180

x = 180 - 164 (subtraction property of equality)

x = 16°

Answer:

Right of X = 368.5

Step-by-step explanation:

By using the normal approximation to the Binomial random variable, we normally make use of continuity correction.

Using the rule of continuity;

P(X > K) turn out to be P(X > K + 0.5)

To determine the required probability:

∴

P(X > K) turn out to be P(X > K + 0.5)

P(X > 635) turn out to be P(X > 368 + 0.5)

⇒ P(X > 368.5) to  the right.  

Right of X = 368.5

Assuming there can only be 2 cookies per identical package, She can make 42 identical packages which contains 2 chocolate chip cookies and 1 sugar cookie.

86 / 2 = 43 chocolate chips cookies

42 / 1 = 42 sugar cookies

With the sugar cookies not having the capability to match the requirements we will assume for this answer that an "Identical Package" is composed of 2 chocolate chip cookies, and a single sugar cookie.

Answer

10 hours

Explanation

Step one:

given information

Company A

charges $45 per hour and a $150 equipment fee.

Let A represent the amount Company A would charge for  t hours

So, the expression for the total is

A= 45t+150--------------------1

Company B

charges $35 per hour and a $200 equipment fee.

Let B represent the amount Company B would charge for  t hours

So, the expression for the total is

B= 35t+200--------------------2

Step two:

equating the two equations above

A=B

45t+150=35t+200

collect like terms

45t-35t= 200-150

5t=50

divide both sides by 5

t=50/5

t=10

Answer:

There are 7 tenths

Step-by-step explanation:

The tenths spot is the first spot over to the right of the decimal place, so there are 7 tenths

As we know that 10 tenths are there in 1 so, there are total 27 tenths are there in the 2.7

The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.

They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.

As per the given information in the question,

10 tenths make up one, hence there are,

2.7 × 10 = 27 tenths in 2.7

There is one more way to check this,

2.7 ÷ (1/10)

= 2.7 × 10

= 27

Answer:

a. t`= 7.63

b.υ = [s₁²/n1 + s₂²/n2]²/ (s₁²/n1 )²/ n1-1 + (s₂²/n2)²/n2-1

= 18.885 ≈19 The degrees of freedom is always rounded in this calculation.

c. The critical region for one tailed test for alpha= 0.1 and 19 degrees of freedom is 1.328= 1.33

The critical region is ║t║` ≥ t 0.05,19 = 1.729= 1.73

A. Reject H0 because the computed tSTAT test statistic is greater than the​ upper-tail critical value

Step-by-step explanation:

Answer:

Step-by-step explanation:

We state our null and alternative hypothesis as

H0: μ1=μ2 against Ha: μ1 ≠ μ2

The level of significance is α=0.1

Since the population have unequal variances , the test statistic if H0 is true ,is

t`= x1`- x2`/ √s₁²/n1 + s₂²/n2

which has approximately a t- distribution with υ degrees of freedom where

υ = [s₁²/n1 + s₂²/n2]²/ (s₁²/n1 )²/ n1-1 + (s₂²/n2)²/n2-1

Computations:

t`= x1`- x2`/ √s₁²/n1 + s₂²/n2

t`= 46-31/ √4²/9 + 5²/12

t`= 15/√16/9 +25/12

t`= 15/ √64+75/36

t`=15/1.9649

t`=7.6339

t`= 7.63

υ = [s₁²/n1 + s₂²/n2]²/ (s₁²/n1 )²/ n1-1 + (s₂²/n2)²/n2-1

= [139/36]²/ (16/9)²/8 +(25/12)²/11

= 14.91/ 0.395 + 0.395

= 18.885

≈19 The degrees of freedom is always rounded in this calculation.

The critical region is ║t`║≥ t 0.05,19 = 1.729

Since the calculated value of t` falls in the critical region we reject our null hypothesis of equal means.

Answer:

(θ) = 84°

Step-by-step explanation:

Given:

sin(θ)=cos(6)

Find:

value of θ

Computation:

sin(θ)=cos(6)

We know that

cos(90-a) = sin(a)

So,

sin(θ)=cos(90-84)

sin(θ)=sin(84)

So,

(θ) = 84°

The value of (θ) = 84°

Given that,

Based on the above information, the calculation is as follows:

sin(θ)=cos(6)

We know that

cos(90-a) = sin(a)

So,

sin(θ)=cos(90-84)

sin(θ)=sin(84)

So,

(θ) = 84°
